Re: I always switch off at the wall now.

"Over-long or over-tightened screws on the VESA bracket at the back, shorted something out. Big bang when next switched on."

Or, more likely, screws got mixed up and short ones went in where long ones should go and vice versa. Been there, done that, and now always lay out the screws in the right order/pattern for putting them back in.
